Unleash The Beast!

The TB12 Tone Beast Black from Warm Audio is a fully professional preamp design with loads of gain that can effortlessly capture an array of sources very well.

It is a swiss army knife full of options and tones!

With top notch CineMag transformers and multiple discrete signal paths, it's hard to beat the Tone Beast's big, bold, fully-professional sound at this price.


  • Discrete 312 preamp design with Cinemag transformers delivers stellar tone
  • Choice of Melcor or Jensen op-amps for varying character
  • Op-amps are socketed/swappable — add your own op-amps to the mix!
  • Choice of steel or nickel output transformers provide more tonal options
  • Choice of tantalum or electrolytic capacitors for even more character variation
  • Transformer bypass switch provides an ultra-clean character
  • Tone switch allows for variable mic impedance
  • 80 Hz highpass filter cuts the mud and rumble
  • 20 dB pad tames really loud sources
  • Output attenuation for saturation flexibility of both op-amps and transformers
  • Insert allows the use of inline processors
  • LED VU meter lets you monitor your levels

The Tone Beast Black is a mic pre that likes to be pushed and when pushed will colourise your signal ever so sweetly.

The 2 opamps and 2 output transformers at the flip of their switches won't appear to be much different, but as one drives the pre into harmonic distortion, the unique character of each of these components becomes apparent.

The Tone Beast Black is customizable and allows users to source and swap in their own opamps. The output control on the TB12 allows you to limit the signal exiting the preamp even when pushing the gain to really hot levels, giving you maximum control.

When designing the TB12 Tone Beast Black our goal was to make a microphone preamplifier affordable and jam packed full of options, without compromising the quality and design parameters that make this type of microphone preamplifier so desirable.

Premium Components

The TB12 "Tone Beast Black" is a fully discrete, high-voltage microphone preamplifier, utilzing CineMag USA Transformers.

Have no fear of hurting the Beast, you can push it very hard into full-on distortion if you wish, and these can sound quite nice on electric guitar, bass or anything else that likes some grit.

The different component options in the TB12 are subtle, but when driven into saturation are noticeable and can make a big difference to the way your final mix will sound.

Home-based musicians and professional studios alike will find the Tone Beast Black to be an extremely powerful and fully professional piece of gear that is capable of warming and shaping signals/mixes in a way that is very pleasing to the ear.


Example Setups:


In this example, a microphone is feeding into a preampflier, which feeds into the WA76 via a balanced XLR patch cable, which feeds into the LINE LEVEL input of your recording interface or mixer.


In this example, the TB12 is being routed as an insert into a recording device. This is useful for using the TB12 as an “analogue plug-in” or insert for mix-down. The recording device is feeding the TB12 with a balanced 1/4” cable via a line output. Then, the recording device is capturing the TB12 via a LINE LEVEL input.

Note: It is important to use a line level input on your recording device as opposed to a microphone or instrument level input.
